I’m so sorry to hear about your migraines- I deal with them too and I know they are no fun at all 
When they get ready bad, I’ve found the fastest way to get them under control is to go into a dark, quiet place away from people and noises, cover my head with a blanket, and focus on deep breathing. The dark, quiet, and calm helps to ease the pain, although it can take some time to get back to normal.
Yes, she has some amazing herbal recipes, and I believe she has very kindly shared a tea specific to migraines here in the forum! Let me see if I can find it…
Here it is: Migraine Tea (and there’s also a Migraine Oil)
While digging through the archives I also found a lovely Self Love Anti Migraine Bath Tea by @Ostara that might interest you too! 
I see there are some lovely recipes and advice already shared here too- I hope that you’ll find plenty of methods that help you to have on hand any time the migraines act up!
Wishing you all the best, Eva- much love and many blessings
